What is Proto.io?
Proto.io's public output has dwindled to occasional customer case studies.
The feed is sparse and old: one case study from mid-2025 (Trenaro's AI learning prototype), another from late 2023 (Travelnaut), and the rest is a 2022 cluster of design listicles and prototyping how-tos. There are no product release notes, no feature posts, and no recurring publishing cadence. The pattern reads like a tool in maintenance mode that still picks up occasional notable customers.
What is Octopus.do?
Octopus.do spends October on the canvas: compact layout, statuses, sticky notes, arrow labels.
Octopus.do is a sitemap and content-planning tool that became agent-operable in August through ChatGPT and Claude apps, an MCP server and a REST API. September added team features; since mid-October it has shipped canvas work: a Compact layout for large sitemaps, project statuses, sticky notes that move with pages, and labels on arrows.

Proto.io
0.0DESIGN
Proto.io's public output has dwindled to occasional customer case studies.
◆ Current state
The feed is sparse and old: one case study from mid-2025 (Trenaro's AI learning prototype), another from late 2023 (Travelnaut), and the rest is a 2022 cluster of design listicles and prototyping how-tos. There are no product release notes, no feature posts, and no recurring publishing cadence. The pattern reads like a tool in maintenance mode that still picks up occasional notable customers.
◆ Where it's heading
Without product-change posts in the visible window, the trajectory signal is mostly negative: long gaps between posts, no roadmap commentary, no feature drops. The 2025 Trenaro case shows Proto.io still being chosen for AI-product prototyping, but doesn't indicate the platform itself is evolving in that direction. The most defensible reading is a stable, low-investment tool.
◆ Prediction
Most likely next signal is another sporadic case study rather than a product release. A material shift would be visible as a return to a regular publishing cadence — until then, expect quiet.
Octopus.do
5.0DESIGN
Octopus.do spends October on the canvas: compact layout, statuses, sticky notes, arrow labels.
◆ Current state
Octopus.do is a sitemap and content-planning tool that became agent-operable in August through ChatGPT and Claude apps, an MCP server and a REST API. September added team features; since mid-October it has shipped canvas work: a Compact layout for large sitemaps, project statuses, sticky notes that move with pages, and labels on arrows.
◆ Where it's heading
After the agent integrations and team layer, the product is refining the sitemap itself as a review artifact that clients and teams can annotate and approve. The releases are small and steady, roughly weekly.
◆ Prediction
Expect more review-workflow features such as approvals or status-based filtering; the entries don't show new agent or MCP work since August.
